I have duplicated the photon cannon to make another building, and I still have the old photon cannon range displayed when I am placing the building.
Is there a way to change the radius? Where is the actor or the thing that trigger that range to display?
How can I do the same for other buildings?
I have searched almost everywhere and I can't find anything that could be related to it...
In the long term I would like to display a range, even after the building creation, or just when we place a building like the pylon power radius for example.
Duplicate actor called "Placement Model" and lets call it "actor 1" (for short). Duplicate actor called "Missile Turret Protect Range" and lets call it "actor 2". In actor 1 in events add event; message type - actor creation. Add term - ModelName - here select model of your photon cannon. Add action - create and select actor - select your actor 2. Go to actor 2 and go to events. Now depends when you want to display your range to pick event, but for example if you want it to show up when u click it (default) select "selection update (local)". Add action "create" and select custom. Below, in token select weapon of your custom photon cannon. Here you can also check who you want to display range to in "visible to:" option. That's the way i do this, hope it helps. For any more weapons you want just add events to actor 1 and create more actor 2's with your new weapons. To get rid of range you already have search for actor that has actions related to your photon cannon and delete them.
 I searched a little and there is actor called "PhotonCannonPlacementModel (unnamed)" which has event that creates range for photon cannon weapon. Try removing it.
